Tire Manufacturing

Manufacturing a tire not only requires the latest technology, precision instruments and qualified people but also requires qualified suppliers.

Working together with our customers and leading research institutions, we have developed a full range of belting products for the Tire Industry.

With the unique product portfolio of fabric based Process and Conveyor Belts, as well as uni Modular Belts, Ammeraal Beltech provides the best technical belting solutions for all tire manufacturing processes.

Batch Off / Dip Tank and Wig Wag

The mixed rubber compound needs to be stored on pallets before the next manufacturing steps are coming. To avoid that the rubber sticks together it is dipped in a soapy water bath, cooled and stored with a wig wag unit on pallets.

Our Modular Belts with the biggest open structure in the market to guarantee a good soap / water penetration in the dip tank

Unique ZipLink® range for easy installation and less downtime

Fabric / Steel Cord Calendering

This is a mechanical process by which rubber is pressed into textiles (cloth, fabric) or steel cords to form composite sheets. Calendered textiles are used for casing, cap plies and chafers. Calendered steel cord is used for belts.

Ammeraal Beltech Synthetic Belts with different covers specially chosen for the used cutting methods

Quick fastener solution or welding solutions for timing belts

Our AmWind liner solutions

Tire Tread and Sidewall Extrusion

Extrusion is the process by which heated rubber (176 °F - 248 °F) is pushed, under high-pressure, through an extruder head, to pre-shape the rubber. The next step is the cooling line where the rubber (tread, sidewall) is cooled and the dimensions are stabilized. The new semi products need to be stored before the next production step (TBM) and this is done via winding units (liner) or other storage systems.

Main challenges

Friction on the feeder belt must work perfect (no slippage but still good release)

No mechanical fasteners allowed due to possible imprint on the rubber

Long cooling lines are needed to cool down the rubber

Pollution or waste due to damaged liner materials

Solutions

Ammeraal Beltech synthetic belts with impregnation to have non-stick characteristics

Our plastic modular belts with an open structure to guarantee a good water penetration in the cooling lines

Non fraying liner material to avoid rubber pollution

AmWind liner solutions

Innerliner Calendering

This is a mechanical process by which multiple rubber layers are pressed in a multi-roll calender towards one homogeneous rubber layer. An alternative is rollerhead equipment. The rubber compound plasticized in the extruder is conveyed via a wide extrusion die directly into the roll nip of a two-roll calender.

Main challenges

Rubber can be sticky (bad release properties of the chosen belt)

Solutions

Ammeraal Beltech Synthetic Belts with impregnation to have non-stick characteristics

Our Modular Belts for longer lifetime and less maintenance

AmWind liner solutions

Tire Building

The first step in final finishing involves the tire-building machine (TBM), with over 40 components that work to form the green tire.

Main challenges

Rubber does not release from belt

Low coefficient of friction between belt and rubber causes rubber to slip

Many parallel running timing belts to accommodate extra-wide rubber leads to different elongation and mistracking

Solutions

Ropanol Belts offer good release of sticky rubber

Grip covers available

Ultrasync Belts with widths up to 1000 mm

Tire Curing

Curing is the process of applying pressure to the green tire in a mold in order to give it its final shape, and applying heat energy to stimulate the chemical reaction between the rubber and other materials.

After the tires are cured in the press, they are often cooled down on a conveyor belt and then transported to the trench line (collector line).

Main challenges

Temperature impact during cool down phase

Mistracking of the conveyor due to temperature impact and wrong material combination

Solutions

Ammeraal Beltech heat resistant Modular Belts

Our roller top belts for the trench line

Inspection and Finishing

After the curing presses, the tires are cooled before going for inspection and collecting. Finished tires need to be handled with care, so transfer roller belts are used for conveying.
